Interesting, I see possible mutual assistance between this project and MisterFPGA, MARS and other FPGA projects. I guess the real difficulty is getting a fab set up to manufacture the chips. Once again, maybe they can take a page out of another project's book like armsid or, more aptly the Apollo line of computer upgrades and cycle accurately emulate the functionality in some other freely available silicon.

Get a cheap PIC or AVR microcontroller, put it on a DIP-sized carrier board, and write a program to simulate everything you'd see on the data/address and any other IO pins of the Z80 when they are manipulated.
